Is there a way to calculate the distance between objects on a map in FMB?

What is the distance between two major longitude or latitude lines (e.g. 318.0 and 319.0) ?

What is the distance between two secondary lines (e.g. 318.0 and 318.1)?

As I zoom in further on a map, the resultion of the grid lines increases, so what is the distance between the closest grid lines if I'm zoomed all the way in?

I'm looking into making a custom made bombing practice target and I figured I would place concentric circles of objects around a center point that are spaced 50 meters apart (i.e. radius= 0, 50, 100, etc.).

Any ideas how to do that?
Also, any ideas what type of objects? they should be rather small, single objects. I tried using the barrels (object 66), but they are always in groups.

Thanks,
Shmulik.

The map grid is in km so:

What is the distance between two major longitude or latitude lines (e.g. 318.0 and 319.0) ? 319.0 - 318.0 = 1.0km

AND

What is the distance between two secondary lines (e.g. 318.0 and 318.1)? 318.1 - 318.0 = 0.1km = 100m

As I zoom in further on a map, the resultion of the grid lines increases, so what is the distance between the closest grid lines if I'm zoomed all the way in? If I recall correctly, it depends which map you're looking at, but you can always work it out from the numbers on the left/bottom edge which are (again if I recall correctly) on every tenth gridline regardless of scale.

Indeed "The MAN..by popular vote". http://forums.ubi.com/images/smilies/11.gif

I was afraid the grid was in real world longitude/latitude lines, and I would need to convert from degrees-minutes-seconds into nautical miles... http://forums.ubi.com/images/smilies/53.gif I even went to wikipedia to learn how this conversion is done, and found out that on degree of latitude is about 111km - that should have got me started, right? http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

These pics i posted a while ago showing distances.Thought they might help. http://forums.ubi.com/images/smilies/shady.gif

In order of closest zoom (3D) to zoom out the grids are typically metric at 10 m, 100 m, 1 km, 10 km then in some cases it becomes 20 km.

Another way of calculating distances. Not very practical but very precise. Put an static objet that you will recognize at each end of the distance you want to mesure. Save your mission and then open it in notepad. Find those 2 objets and do the following calculations:

object 1 coordonates: X1, Y1 (mm)
object 2 coordonates: X2, Y2 (mm)

Distance = square root ((Y2-Y1)^2+(X2-X1)^2) in mm

If you want km then divide that number by 1 000 000

As previously posted, set a Fiesler Storch at the beginning and ending waypoints, set to 100km/hr and do the math. Works for any angle, any distance.
